Hello,
I have an optimization block together with a S-parameter block in my design.
Sometimes I want to simulate only the S-parameter and not change the
variable values inside the optimization block.
Is there a easy way to do it?
- If I deactivate the optimization block, the variables are no longer defined.
- I could have an equation block, that defines the variables and have either this
one or the optimization block activated. But this way, i would have to make
sure, that the variable values in the optimization and in the equation block are
the same.
- I could tweak the optimization parameters, so that the optimization is finished
in no time, but this could change the variable values.
- It would be cool, if the optimization block could be 'shorted', like a resistor, but
I'm not sure, if that would be too confusing.
Best Regards
Carsten

Hi Stefan.
I have managed to get the pinout from the circuit symbol for
the IC component to line up with the solderless breadboard
layout.
I have left it as an example on the breadboard template,
which I will be sending to you soon.
Kind Regards,
Keith Roberts

Nope, you'll need to create your own symbol for that...
